On Capitol Hill today, 68 members of the U.S. Senate, the world’s greatest deliberative body, voted “aye” on the question of whether it’s okay to talk about gun control.

The law on which debate will soon begin includes, among other things, an expansion of background checks for gun buyers.

Progress on anything in Washington lately has been incremental at best. On gun control in particular, states and cities are moving faster, and one thing they’re considering is taxing guns and ammunition.

Since April 1, Cook County, home to Chicago, has had what it calls a “violence tax.”

Revenues go to the Cook County Health & Hospitals System. Last year, it treated more than 800 victims of gun violence, at an average cost of $52,000 per patient.

Lutger says he’s concerned about the level of gun violence in Chicago, but he points out Tinley Park is in the suburbs, a half hour from downtown.

“They gotta curb it,” he says. “But this isn’t the way to do it.”

Politicians in many cities and states think it is.

Nancy Staudt, the Edward G. Lewis Chair in Law and Public Policy at the University of Southern California, says a tax on firearms isn’t unlike other taxes on tobacco or alcohol.

“Individuals who want to own guns, that’s fine,” she says, noting many constitutional rights are not limitless. “The Second Amendment allows you to own guns, but there are certain costs to society of owning that gun, and you’ll need to help pay for those.”

The California State Assembly is considering a five-cent tax on each and every bullet, to pay for an early childhood mental health program. Next door, Nevada is considering its own tax -- on both ammunition and firearms, to pay for mental health services and to help crime victims.

“It sends a message to Washington that this is important to us,” says Nevada Assembly Majority Leader William Horne, who sponsored the bill.
